What's happening
A lower-than-expected AI chip forecast from Broadcom in early June 2026 triggered a broad semiconductor sell-off that erased more than $1 trillion in chip-stock market value in a single trading session. The event pulled Nvidia to approximately 16% below its 52-week high of $236.54, with shares recently trading near $198.19, while AMD declined to roughly 8% below its 52-week high of $562.99, with shares near $518.33.
Against that backdrop, both companies had recently reported quarterly results that reflected continued momentum in AI-driven data center demand. Nvidia's fiscal Q1 2027 (ended April 26, 2026) showed revenue rising 85% year-over-year to $81.6 billion, with data center revenue up 92% to $75.2 billion. The company guided for approximately $91 billion in Q2 2027 revenue, representing roughly 95% year-over-year growth at the midpoint, assuming no contribution from China data center revenue. AMD reported Q1 2026 revenue of $10.3 billion, up 38% year-over-year, with data center revenue climbing 57% to $5.8 billion, adjusted EPS rising 43% to $1.37, and record free cash flow of $2.6 billion. AMD guided for approximately 46% revenue growth in Q2 2026.
Why it matters for markets
The sell-off has created a measurable gap between the two companies' valuations relative to their recent highs, and the underlying financial metrics highlight a significant divergence in margin structure and earnings multiples. Nvidia carries a trailing P/E of approximately 30.5 and a forward P/E of roughly 23, supported by a non-GAAP gross margin of 75%. The company also added $80 billion to its share repurchase authorization and returned approximately $20 billion to shareholders in the most recent quarter, underscoring the scale of its cash generation relative to its $4.82 trillion market capitalization. AMD, by contrast, trades at a trailing P/E of approximately 172.7 and a forward P/E of roughly 74, against a market capitalization of approximately $848 billion — a premium multiple that reflects growth expectations but leaves less margin for error if those expectations are not met.
The contrast in gross margin profiles is particularly relevant in the context of a demand-uncertainty event like the Broadcom forecast revision. Nvidia's 75% non-GAAP gross margin provides a wider buffer against potential revenue shortfalls, while AMD's margin structure and higher earnings multiple mean its valuation is more sensitive to changes in forward growth assumptions. AMD's record $2.6 billion in free cash flow for Q1 2026 demonstrates improving cash generation, but the gap in absolute scale — Nvidia's trailing revenue of $253.49 billion versus AMD's $37.45 billion — reflects the degree to which Nvidia has captured a disproportionate share of AI infrastructure spending to date.
The Broadcom forecast that catalyzed the sell-off introduced uncertainty about the pace of AI chip demand, a question that bears directly on both companies' ability to sustain the growth rates embedded in their current valuations. Nvidia's Q2 guidance of approximately $91 billion — which explicitly excludes any China data center contribution — suggests management has already discounted a meaningful revenue source, which could represent either a conservative floor or an indicator of ongoing geopolitical constraints on its addressable market.
Sectors and assets to watch
The semiconductor sector broadly, and AI accelerator suppliers specifically, remain the primary area of focus following the sell-off. Nvidia (NVDA) and AMD (AMD) are the two largest publicly traded pure-play GPU and AI accelerator companies, and their post-selloff valuations will be closely monitored as data center capital expenditure commitments from hyperscalers are updated through the remainder of 2026. Nvidia's data center segment, which generated $75.2 billion in Q1 2027 alone, and AMD's data center segment at $5.8 billion in Q1 2026, are the key revenue lines to track for evidence of demand stabilization or further softening.
Broadcom, whose lower AI chip forecast served as the proximate trigger for the sell-off, will remain a reference point for sector sentiment. Beyond the primary chipmakers, the broader AI infrastructure supply chain — including networking, memory, and advanced packaging suppliers — may also experience valuation adjustments as the market recalibrates expectations for the pace of AI buildout. Any revision to hyperscaler capital expenditure guidance in upcoming earnings cycles will be a key input for reassessing demand trajectories across the sector.
What to watch next
Key developments to monitor include Nvidia's fiscal Q2 2027 earnings, which will test whether the company can deliver on its approximately $91 billion revenue guidance — and whether any China data center revenue materializes beyond what was assumed in that forecast. AMD's Q2 2026 results will similarly be scrutinized against its approximately 46% revenue growth guidance, with particular attention to whether data center momentum is sustained. Any updates from major hyperscalers on AI infrastructure capital expenditure plans will serve as leading indicators for both companies' forward demand. Additionally, further commentary from Broadcom or other semiconductor suppliers on AI chip order trends will be watched for signals about whether the early June forecast revision represented a temporary recalibration or a more durable shift in demand expectations.
